Hi everyone,
First of all I hope I've posted this in the right section as I'm new but in need of advice. My dad drives a 2004 Vectra C 2.2 direct that is unfortunately having some issues. I've read a ton of threads and most of the time the cause is the HP pump, however we've changed that less than 19,000 miles ago (about 5 years as we don't drive outside of town much). Brand new Continental pump as the Siemens one gave up.
Car is now having similar problems but not the same as when the Siemens died. Current symptoms are:
Idling is a little rough, no misfires but lower than usual and you can feel the car shaking a bit.
Car runs absolutely fine until about 4200rpm where sometimes it would stop accelerating, take a second and then reach 5000rpm where it would go into limp mode or just straight limp mode from 4000rpm.
Sometimes it won't start properly or at all.
MAF is new, sparks are new and coil pack was changed about 5,000 miles ago.
Since there isn't an Opel dealership where we live and my dad is worried the car might die on the road to one, it went to a local shop to check for fault codes where they told him they've read Fuel Pressure System malfunction. I get an idea what that might mean but I hope it's not the pump again but rather the fuel pressure regulator or maybe something else. I'm posting this in hope of someone that has gone through like this and might have an idea.
Apologies for the English, as I'm not from/in the UK.
